We did the cut and weld procedure on my RV-8 stick with the Tosten grip. It works well, but the stick is so far back in the flare that my cuff deficient shoulder doesn't work as well to control the flare as it did with the short stick. I still think it's an improvement but might require some fine-tuning. Will try to post some pics. We used a PVC dummy stick to plan the cuts.
